Definitions
- the present invention is related to a surgical aspiration device, which is intended for use in surgical operations for removing blood, other liquids and/or matter from the operation area.
- the object of the present invention is to obtain a surgical aspiration or suction device by which blood, wound secret and solid matter can be removed during an operation, whereby aspiration can be done either in an atraumatic manner or for dissection and suction of tissues.
- a surgical suction device which comprises a point aspirator and an outer aspiration tube arranged round the point aspirator, wh ereby t h e outer tube is axially displaceable in order to enable point aspiration or sump aspiration.
- the suction device is produced to enable alternative point or sump aspiration, i.e. aspiration in a limited area, or aspiration for removal of larger amounts of liquid from a greater area. This aspiration twice cannot be made work in an atraumatic manner, and on aspiration tissue will be invaginated by suction adheration.
- the inve ntion relates to a surgical aspiration device comprising a tubular handle, which at one end thereof has an outlet for connection to a vacuum source, and which at the other end thereof has a projecting point aspirator shaped as a tube which at least at its front end is provided with an axially (frontally) arranged aspiration opening.
- the invention is characterized in that the handle further is provided with an outer tube arranged substantially concentically with the point aspirator, which outer tube extends along the entire point aspirator and which has an opening at its front, end adjacent to the front end of the point aspirator, whereby an interstice is arranged between the outer tube and the point aspirator, and whereby the outer tube has an air inlet opening adjacent to the handle, through which opening air is allowed to pass along the outside of the point aspirator to the aspiration opening thereof.
- An embodiment of the invention is characterized in that the outer tube extends further beyond the. front end of the point aspirator.
- a further embodiment of the invention is characterized in that the point aspirator is arranged without any joint. to the outer tube at its front end.
- a still further embodiment of the invention is characterized in that the outer tube and the point aspirator are joined to each other at the front ends thereof, whereby the point aspirator has at least one laterally arranged opening, adjacent to the front end thereof for connection between the. interior of the point aspirator and the interstice.
- a further preferred embodiment of the invention is characterized in that the point aspirator at its front end has at least one further laterally arranged opening connecting the interior of the point aspirator with the interstice.
- Another preferred embodiment of the invention is characterized in that the outer tube is held axially displaceable in relation to the handle.
- a further embodiment of the invention is characterized in that the ratio between the cross-sectional area of the point aspirator and the cross-sectional area of the interstice at the front end is 1:1-1.4.
- Another further embodiment of the invention is characterized in that the diameter of the air inlet opening is substantially equal to the outer diameter of the point aspirator.
- the present invention is achieved a continuous flow of air during aspiration, in the direction opposite to the flow of liquid, on the outside of the point aspirator to the tip of the mouthpiece, where the air breaks the liquid column that would otherwise be formed.
- the air in the aspiration device and the aspiration tube connected the to expands at an increased vacuum in the tube, in contrary to the liquid, and thus counterbalances the increased suction force.
- the aspiration device can be used with a maximal vacuum, as produced by the central vacuum installations in hospitals.
- Fig. 1 shows an aspiration device according to the invention in section along its length axis
- Fig. 2 is a section in accordance with Fig. 1 of a bent aspiration device according to one embodiment of the invention
- Fig. 3 shows the section III-III in Fig. 2
- Fig.4 shows the section IV-IV in Fig. 2
- Fig.5 shows a further embodiment in accordance with Fig.
- F ig. 5 s hows the sect i on VI -VI i n F i g . 5 . 1 denotes a substantially cylindrical handle having a longitudinal bore 2.
- the handle is at one end thereof provided with a connection means 3 for connection to tube (not shown) for further connection to a vacuum source (not shown).
- the handle 1 is at its other, front end provided with a point aspirator 4 shaped as a tube which extends forwardly to a suitable distance from the handle.
- the aspiration device may be made of plastic material or glass, whereby a plastic material is preferred when the device is to be disposed of after use once.
- the point aspirator 4 is open at its front end 5 but is also suitably provided with a number of openings 6 arranged laterally hear the orifice 5 of the tube.
- an outer tube 7 is arranged at the front end of the handle concentrically round the point aspirator 4 in such manner that an interstice 8 is present between the inside of the outer tube 7 and the outside of the inner tube 4.
- the outer tube 7 is provided with a laterally arranged air inlet opening 9 adjacent to the front end of the handle 1, which opening 9 connects the interstice with the exterior.
- the opening 9 in the tube can be shaped as shown so as to anatomically fit with a finger tip for control of the size of the opening 9, i.e. the degree of connection between the interstice and the exterior in this part.
- the outer tube 7 should also extend beyond the inner tube 4 in the manner shown in figs. 1 and 2 to ensure breaking of the liquid column.
- the outer tube shall thus extend 1-5 mm forwardly beyond the inner tube 4, whereby the tip of the inner tube is to be placed at a distance backwards in the outer tube 7 equal to the outer diameter of the inner tube' 4.
- the outer tube 7 here has a frontal opening 11.
- the ratio between the cross-sectional area of the inner tube and at the tip thereof and the cross-sectional area of t he a ir s pace between the ou ts ide of the i nner tu be 4 and the inside of the outer tube 7 shou ld be
- the diameter of the air inlet opening should be equal to the outer diameter of the inner tube and should be placed as far back towards the handle as possible.
- Fig. 5 shows another further preferred embodiment of the aspiration device according to the present invention, whereby the inner tube 4 is extended and joined with the outer tube 7.
- the inner tube has thereby been provided with a number of side openings 10, suitably three, by which the aspirated air can pass into the inner tube 4 on use of the aspiration device.
- the front end of the aspiration device can then be shaped as shown in Fig. 5 with a rounded tip prepared by bending in and joining the outer tube 7 with the inner tube 4, or by narrowi ng and joining the outer tube 7 with the inner tube 4.
- the side openings 10 are then placed as far forwardly as possible without impeding free passage of air from the air space/interstice between the inner tube 4 and the outer tube 7.
- the added area of the side openings should not beless than the cross-sectional area of the inner tube 4.
- the outer tube 7 can also be held axially displaceable in relation to the handle 1, whereby the position of the outer tube 7 relative to the point aspirator, i.e. the inner tube 4, can be varied, thereby varying the amount of air aspirated at the tip of the point aspirator, and further, the air inlet opening may be covered more or less whereby the amount of air flowing through the interstice 8 may be varied.
- the aspiration device On use of the aspiration device according to the invention it is connected at its connections means 3 to a tube connected to a vacuum source, such as a central surgical aspiration source or the like.
- the aspiration device is then lowered into the operation area at a surgical incision on a patient.
- the operator can now, depending on the amount of liquid or matter to be removed, elect to close or not close the air inlet opening 9 with a finger tip. If large amounts of liquid are to be radically drained the opening 9 is closed whereby maximal suction effect is obtained, while in case of risk of invagination of sensitive tissue parts the operator holds the opening 9 open so that air may always break the liquid column aspirated through the tip, i.e. the negative pressure at the tip is reduced so as to. prevent harmful invagination.
- the amount of air let in through the opening 9 can also easily be adapted to the conditions by covering said opening more or less with a finger tip.
